What it powers at the humanitarian hub in Dikwa
Dikwa is a regional office with guest rooms for humanitarian staff, and it's growing. It runs about 27 air conditioners, plus water heaters, kitchen equipment, fridges and freezers, lighting and internet.
How we split the loads
We wired the hub into two circuits, so the things that matter most never go off.
Critical loads: always on
Lights, fans, computers, internet, fridges and security run on the battery 24 hours a day.
Heavy loads: smart control
Air conditioners, water heaters and kitchen equipment switch off when the battery drops to 40% and come back on at 60%.
What we did
✓ Installed 120 JinkoSolar bifacial panels on the hub roofs
✓ Installed 2 Deye 50 kW hybrid inverters and 10 battery racks in a temperature-controlled power room
✓ Ran the system at full load for 48 hours before handover
✓ Trained the hub team to run and check the system
Full equipment list
• 75 kWp: 120 × JinkoSolar 625 Wp bifacial panels
• 100 kW inverter capacity: 2 × Deye 50 kW high-voltage hybrid inverters
• 614.4 kWh storage: 10 × Deye 61.44 kWh high-voltage battery racks
• Off-grid hybrid with generator backup
• Remote monitoring on DeyeCloud

How the load control works
We sorted every circuit in the hub with the client's technical team. Critical loads sit on the battery circuit and never go off. Heavy loads sit on a separate, controlled circuit. The system runs everything from full battery down to 40%. At 40%, it switches the heavy loads off and waits for the next morning sun. At 60%, it turns them back on. The generators stay as a manual backup, so the hub team can see and manage how much energy the hub uses.
